COMBINED CLOSURE AND EBASER FOR FOUNTAIN-PENS.

Specification of Letters Patent.

Application filed March 14, 1916, Serial No. 84,154. Renewed October 9, 1918. Serial No. 257,536.

To all whom it may concern:

Be it known that I, STANLEY NEWELL, a citizen of the United States, residing at lVapello, in the county of Louisa and State of Iowa, have invented new and useful Improvements in Combined Closures and Erasers for Fountain-Pens, of which the followi is a specification.

his invention relates to a combined closure and eraser and more particular to a clocompensating for Wear.

Another object of the invention is the novel manner of associating the elements so that upon movement of the support within the tubular member the erasing element will be moved in a direction to compensate for the Wearing action.

With these and other objects in view, the invention consists in the construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the claims hereunto appended.

In the drawings g Figure 1 is a side elevation of the fountain pen shown in my attachment applied thereto, the cap being removed.

Fig. 2 is an enlarged Vertical sectional view of my. invention. Fig. 3 is a detailed view of the erasing element.

Fig. 4: is a detailed view of the support.

Fig. 5 is a sectional view on the line 5--5 of Fig. 2.

Fig. 6 is a sectional view of the support.

Referring to the .drawing, the numeral 1 designates a tubular member forming when associated with the cap 2 a closure of a shape corresponding to the shape of the fountain pen cap now in use. The member lat an intermediate point has a partition 3. and that portion of the interior of the member 1 from the partition 3 to the adjacent end of the tube, is screw threaded.

Cooperating with the threads 4 are the threads 5 upon a support 6. This support 6 is solid as shown in Fig. 2, whereas in Fig.

smaller opening 8.

An erasing element 9 shown in this partic- Patented May 6, 1919.

ular instance in the form of a brush the bristles of which are made from spun glass, is arranged in the openings 7 and 8-with the result that, that portion of the bristles passing through the opening 8 are more compact than those passing through the opening 7 so as to give greater rigidity to the operating portion 10 of the erasing element, whereas in Fig. 3 the same result is accomplished by the tapering Wall of the passage 10 in the support 6. The opposite end portion 11 of the brush is bound together by the screwing element 12 that in turn bears upon the partition 3 with the result that when the support is adjusted in the member 1, the erasing element will be given a lengthwise movement through the support due to the abutting relation between the partition and end 11 of the brush so as to compensate for wear. The cap 2 has screw threaded engagement with the support so that when the cap is assembled upon the member 1 the erasing element will be invisible.

From the. foregoing description taken in connection with the accompanying drawing, it should be apparent that I provide a device which is admirabl adapted for the purpose for which it is intended, that the device is simple, durable and eflicient of construction, and that the device may be manufactured and sold at a comparatively low cost and in which the elements are so related that the ordinary fountain pen cap and eraser is combined in 'a unitary article.

What I claim is 1. A fountain pen closure comprising a tubular member open at vboth ends, a partition in said member, said member being internally threaded from said partition to the adjacent ends, an erasing brush disposed with its base on said partition and having its outer end extending beyond the end of the tubular member, a compression plug threaded within the threaded portion of said tubular member and provided with a bore tation and the adjacent ends of the tubular member whereby said plug will always project therebeyond, and a closure cap threaded upon the projecting end of the plug.

2. A fountain pen closure comprising a tubular member open at both ends a partition in said member, said member eing internally threaded from said partition to the adjacent ends, an erasing brush disposed with its base on said partition and having itsouter end extending beyond the'end of the tubular member, a compression plug threaded within the threaded portion of said tubular member and provided with a bore tapering toward its outer ends for the passage of said brush, the outer end of said bore being of smaller diameter than the diameter of the base of said brush whereby the outer ends of said brush will be compressed, threading of said plug within said tubular member eifecting a relative longitudinal. outward movement of said brush to take up wear, and a closure cap threaded ,upon the extending outer ends of said plug.

In testimony whereof I aifix my signature Witnesses:
